I need to buy a nic that I want to eventually (~3 months) re-use for a VM server deployment that will need to support heavy network I/O. Server is a Xeon Gulftown/Westmere-EP.
Intel has server NICs that support VMDc, VMDq, or both.
Which is the difference?
Which do I want? They both seem to deal with the problem of doing per-VM segmentation at the NIC level, but I don't know which technology better.
